6.2 Growth and structure of semiconductor quantum wells
... 10 nm. The spectrum of GaAs at the same temperature is shown for comparison. Detailed analysis reveals that the binding energies of the quantum well excitons are about 10 me, higher than the value of 4.2 meV in bulk GaAs. The enhancement is a consequence of the quantum confinement of the electrons a ...

... – It isn’t how easy it is to calculate f(x), it is how many times. – Need to go from 0 to n2 , this is a huge number of calculations for a 128 bit number. This means 2(2*128) or ~1.16 x 1077 – The results have to be stored somewhere (taking up memory) and then we still have find the period! – Or we ...
